Chamomile seeds can be started indoors 3-4 weeks before the last frost. When planting chamomile seeds indoors, fill a seed tray with well-draining potting mix, then simply scatter the seeds over the loose soil.
- Seedlings should be thinned to 2-4 inches (5-10 cm.) apart when they are about an inch (2.5 cm.) tall. Plants do not like to be transplanted once their roots have established and they begin to produce blooms, so many gardeners prefer to sow the seeds directly in the garden.
- In the garden or as a lawn substitute, chamomile seeds need only be scattered over loose soil and gently tamped down.
- Germination can occur in temperatures as low as 45-55 F. (7-13 C) in full sun to part shade.
